OSCILLATORS
Oscillators can be defined as a price derivative Oscillators experience oscillations that permits to identify the volatility in the market Oscillators are the graphic representation of the change in prices and determine the volatility within a market
3 different classes of signals 1. Overbought/oversold ( when the market has gone up/down much)) 2. Divergences ( disconnection between prices and oscillators) 3.Chartism on oscillators
OVERBOUGHT / OVERSOLD Oscillators with limlits (0 à 100) Oscillateur without limits (-X…0….+X) RSI MOMENTUM (Macd, stochastics…)
Oscillator with limits are more informative of market volatility
DIVERGENCE Cannot be seen on prices alone Indicates an exhaustive condition Divergence can only be considered in overbought/oversold conditions
NEGATIVE DIVERGENCE NOT A SELL SIGNAL PROFIT TAKING OPPORTUNITY Alteration of a trend Sell signal ?
CHARTISM ON OSCILLATORS Trend analysis possible on all oscillators Filters on oscillators can be used only in overbought/oversold conditions (RSI with a moving average) A trend break on an oscillator can predict a change in trend but does not give a buying or selling signal
MAIN OSCILLATORS Oscillators with limits Oscillators without limits Other oscillators
Oscillateurs without limits MOMENTUM ROC MACD
MOMENTUM C t – C t-x
Without limit Not a good OB/OS indicator Trend lines Best use for momentum MOMENTUM CARACTERISTICS Best time interval 10 jours
TREND BREAK
ROC C t 100 * C t-x
ROC CARACTERISTICS Very similar to momentum The rises are amplified compared to falls ONE NOTE OF CAUTION : IT IS POSSIBLE FOR ROC INDICATORS TO MOVE TO UNUSUAL EXTREMES WELL BEYOND THE OVERBOUGHT/OVERSOLD EXPERIENCE
DIVERGENCE
THESE LINES ARE TOO CLOSE TO THE EQUILIBRIUM LINE.
THESE LINES ARE TOO FAR APART FROM THE EQUILIBRIUM LINE.
THESE LINES ARE NOT PERFECT BUT THEY ARE A REASONABLE COMPROMISE SINCE THEY ARE CLOSE TO MOST TO MOST OF THE EXTREME POINTS.
Moving Average Convergence D ivergence MACD is calculated by comparing 2 exponential moving averages D is defined as the difference between 2 moving averages E is defined as the moving average of D MBT
THE ZERO LINE CORRESPONDS TO WHEN THE 2 MA ARE IDENTICAL WHEN MACD>0 ST EMA is above LT EMA
MACD CARACTERISTICS Super buying/selling signal whenever MACD intersects E at equilibrium point 0 Wise to doubledeck the linear and histogramme to get a better view Buying signal when the histogramm goes above 0
BUYING SIGNAL
Oscillators with Limits RSI Stochastics
Relative Strength Indicator Market oscillators between 0 (minimum) and 100 (maximum) 100 RSI = RS Average updays in X days RS = Average downdays in X days BAC
RSI CARACTERISTICS Overbought zones ( RSI>70) et oversold zones (RSI < 30) are not pure entry position levels but rather profit taking zones Only when the market exits from that high volatility zone can one initiate an entry position Divergences are only valid in overbougth/oversold zones.
A LOW IN THE BRITISH EQUITY MARKET OCCURED AFTER THE RSI HAD ENTERED IN THE 30 ZONE.
NOTICE HOW THE INDEX KEPT TRADING SIDEWAYS WITH THE RSI CONTINUING TO GO UP !
STOCHASTICS STOCHASTICS TAKES INTO ASSUMPTIONS THAT PRICES CLOSE NEAR THEIR HIGH DURING AN UPTREND AND CLOSE TO THEIR LOWS DURING AN DOWNTREND
PRICES CLOSE NEAR THEIR HIGH DURING AN UPTREND…
AS THE UPTREND MATURES, PRICES CLOSE LOWER THAN THEIR HIGH…
THE GOAL OF STOCHASTICS IS TO DETERMINE THE LEVEL AT WHICH CLOSING PRICES START FURTHERING OUT FROM THE HIGHS IN A STILL RISING MARKET
Stochastic indicators are composed of a first oscillator called %K which is then filtered by a second oscillator called %D C - L x %K = 100 x H x - L x C : Closing price L x : Lowest price in the last X days H x : Highest price in the last X days
K..wick (gives major signal) D..awdling….(more sensitive of the 2) "D" is a moving average of "K"
STOCHASTICS CARACETRISTICS Better than the RSI because it takes into consideration the highs and lows and not only the closing prices Stochastics offer 3 types of levels : : Overbought / Oversold Overbought/Oversold signal with %D and slow%D crossing Trend indicators with divergences
HOW TO INTERPRET STOCHASTICS
1. DIVERGENCES
2. CROSSOVERS "K" WILL OFTEN CROSSOVER "D" BEFORE "D" CHANGES DIRECTION (normal as "K" is Kwicker)
THE INDICATOR IS STRONGER WHEN "K" CROSSES "D" AFTER "D" HAS CHANGED DIRECTION.
3. WHEN THE "K-LINE" REACHES NEAR 100 WITH OVERBOUGHT READINGS IN OTHER INDICATORS AN EXTREMELY HIGH "K-LINE" WARNS YOU OF FURTHER STRENGTH ONCE THE INITIAL OVERBOUGHT LEVELS HAVE NEUTRALIZED.
THAT' S IT FOR TODAY !!!!!
ONE NOTE OF CAUTION : IT IS POSSIBLE FOR ROC INDICATORS TO MOVE TO UNUSUAL EXTREMES WELL BEYOND THE OVERBOUGHT/OVERSOLD EXPERIENCE
THE ADVANTAGE OF ROC IS THAT IT EASILY LENDS ITSELF TO PRICE PATTERN CONSTRUCTION RARE !
THE ROC PRICE PATTERN FORMATION WORKS BETTER AT AN AVERSOLD LEVEL IN RISING MARKETS AND AT OVERBOUGHT LEVELS IN DECLINING MKTS.
RELATIVE STRENGTH INDICATOR
THE RSI IS A FRONT- WEIGHTED PRICE VELOCITY RATIO FOR A SPECIFIC SECURITY Y RELATIVE TO ITSELF AND IS THEREFORE RELATIVE TO ITS PAST PERFORMANCE ONLY ONE OF THE PROBLEMS WITH THE ROC INDICATOR, IS THAT IT IS POSSIBLE FOR THEM TO MOVE TO UNREASONABLE EXTREMES. THE RSI DOES NOT SUFFER FROM THIS DRAWBACK. RSI MEASURES GO FROM 0 TO 100 ALTHOUGH IN PRACTICE THEY ARE RARELY OBTAINED.
RSI MEASURES MOVE INVERSELY TO OTHER MOMENTUM INDICATORS
VERY OFTEN EXCEEDED UPPER AND LOWER LIMITS RARELY ATTAINED YOU SHOULD THEREFORE NARROW THE TIME BAND
6 PRINCIPLES OF RSI INTERPRETATION
1. 70/30 overbought/oversold levels (for 14 days) (narrow bands for >14)
2. LENDS ITSELF TO PRICE PATTERN FORMATIONS, BUT NOT AS MUCH AS ROC
3. FAILURE SWINGS OCCUR WHEN THE RSI TENDS TOWARDS THE EQUILIBRIUM LEVEL IN A RISING MARKET
4. DIVERGENCES
A LOW IN THE BRITISH EQUITY MARKET OCCURED AFTER THE RSI HAD ENTERED IN THE 30 ZONE.
NOTICE HOW THE INDEX KEPT TRADING SIDEWAYS WITH THE RSI CONTINUING TO GO UP !
5. TRENDLINES
DON'T EXPECT MUCH CORRECTION DOWNMOVES IN A BULL MARKET WHEN THE RSI IS AT OVERBOUGT LEVELS SIMILARLY FOR BEAR MARKETS.
MACD MACD IS CALCULATED BY COMPARING 2 MOVING AVERAGES MOVING AVERAGE CONVERGENCE DIVERGENCE METHOD
USE 12 DAYS FOR THE SHORT TERM MA. USE 26 DAYS FOR THE LONG TERM MA.
THE ZERO LINE CORRESPONDS TO WHEN THE 2 MA ARE IDENTICAL WHEN MACD>0 ST EMA is above LT EMA
TOO MANY WHIPSAWS USING SIGNAL LINE …
HOW DO YOU CHOOSE YOUR TIME SPAN DATA ? THE RECOMMENDED COMBINATIONS ARE : 8-17 AND 9 DAYS EMA AND 9 DAYS EMA (BETTER FOR SALES) MARKETS SPEND MORE TIME IN A RISING THAN IN A FALLING MODE
MACDs CAN ALSO BE PLOTTED USING HISTOGRAMS GOOD FOR PEAK AND TROUGHS DIFFICULT TO IDENTIFY PATTERN FORMATION
STOCHASTICS ALWAYS FALL IN THE RANGE OF 0 TO 100 READINGS CLOSE TO 80 INDICATE THAT PRICES ARE CLOSING NEAR THEIR HIGHS AND VICE VERSA.
